Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
browser-harness
Open-source browser agent driven via CDP — direct browser control, 79K stars, YC W25. browser-harness gives Claude Code direct, low-level control of a real Chrome browser via the Chrome DevTools Protocol. Coordinate-level clicks pass through iframes, shadow DOM, and cross-origin frames at the compositor level — no selector hunting, no Playwright wrappers. Connects to a long-running Browser Use Cloud or local browser session, so logins persist across runs. Highlights: - Screenshot-first workflow: capture → read pixel → click_at_xy → re-capture to verify - Bulk HTTP fetch helper for static pages (no browser overhead) - Raw CDP escape hatch for anything helpers don’t cover - Interaction skills for dialogs, dropdowns, iframes, shadow DOM, file uploads, cross-origin frames - Remote browsers via Browser Use Cloud — share a live URL with a human when login/CAPTCHA blocks the agent
